Made extensible, had to remove manual controls (for now)

[Halbann]

Functional WIP. Here is the new MM usage:

@PART[kpaNearSight]
{
	// Remove all existing jettison modules
	-MODULE:HAS[#name[ModuleJettison]] {}

	%MODULE
	{
		name = ModuleAttachmentVisuals

		%NODEVISUAL[top]
		{
			showWhenAttached = TopCap
		}
		%NODEVISUAL[bottom]
		{
			showWhenAttached = BottomCap
		}
	}
}

I think putting the names inside square brackets was what MM read it properly, but I tried percentage signs first and haven't tested without them yet. Probably not needed.
